Name: Brandon Peterson
Position: RHP
Birthday: September 23, 1991
Birthplace: Burnsville, MN
College: Wichita State (1 yr), Des Moines Area CC (2 yrs)
Height/Weight: 6'1", 198 lbs
Bats: R
Throws: R

Summary:
Brandon Peterson is right-handed reliever with a 95 mph fastball. A 2013 draftee from Burnsville, MN, he will start the year in Cedar Rapids. A precision fastball-slider pairing earned him a lot of whiffs in the Appy League without many walks. He had worked as a closer throughout much of his collegiate career and continued to do so in many games at Elizabethton.

History:
Brandon Peterson is a native of Savage, MN, and attended Burnsville High School. He was a key part of a strong 2010 Burnsville Blaze team that finished runner-up to Eden Prairie in the MSHSL AAA tournament.

After high school, Peterson attended Des Moines Area Community College where he compiled a 3.50 ERA, 6 saves, and a 6-1 record in 24 appearances during his freshman season. In his sophomore season, he went 6-4 with a 4.94 ERA and 3 saves in 21 appearances, eight of which were starts.

He attended Wichita State University (like Twins SP Mike Pelfrey) after junior college, pitching well as a closer for the Shockers. He appeared in 26 games and put up a 1.12 ERA in 40 IP. He earned 10 saves and a 3-1 record, holding opponents to a .189 batting average, striking out 42 and walking 15.

The Twins drafted him with the 380th overall pick in the 13th round of the 2013 Amateur Player Draft. According to his MLB.com (http://mlb.mlb.com/news/article.jsp?ymd=20130608&content_id=50017664&notebook_id=50018014&c_id=min) draft writeup, his fastball reaches 95 mph, usually falling to the low 90s. His main secondary pitch is a slider.
After the draft, he was assigned to Elizabethton where he led the Appalachian League with a SO/9 of 13.2. He went 0-2 with a 2.96 ERA in 27.1 IP over 19 games. He walked only 9, striking out 40. He finished 14 games, 5 of which were saves.


Future:
Adopt-a-prospect isn't any fun without speculation about what the future has in store for a young player! As mentioned in the summary, Peterson will begin the year in Cedar Rapids as a reliever. Last year a number of different pitchers were employed by Manager Jake Mauer to close out games. Regardless of whether Peterson earns a de facto "closer" job for the Kernels, he will likely aim to do exactly what he did in Elizabethton where his results were excellent in almost every category. As a 22 year old, 13th round reliever, he doesn't have the hype surrounding the teenage phenoms that have passed through Beloit and Cedar Rapids recently, but continuing to generate results like he did in rookie ball should begin to turn some heads.

Since we're over a week into the season, I figured I'd write a quick update on Peterson's early performance. He has appeared in 3 games (April 5, 10, and 12).
He faced 5 batters in his first opportunity, striking out 2 and allowing 2 hits over 1.1 innings.

His second appearance was a ninth-inning non-save opportunity. He got through the inning by striking out two, but walked a batter and allowed two hits, earning a run in the process.

On Saturday, he pitched a two-inning save, striking out three and walking one on 0 hits.

Not enough to really go on at this point, but so far, Peterson appears to be replicating what he did in Elizabethton: striking out 1 or 2 batters an inning, and allowing the occasional walk. Not bad!

Peterson was brought in for the 9th inning in yesterday's Kernel's game. With CR down by a run, one out, and two runners on, he allowed a groundball single (runner scoring - charged to Christian Powell), struck out a batter, and got a groundout to end the inning.

This line got me thinking: Is there any statistic or measure of a relief pitcher's ability to strand inherited runners? It's probably a off-topic enough to warrant a post in the forums instead of A-a-P. In conventional statistics, Peterson's line isn't hurt by the inherited runner he allowed to score, nor is he rewarded for the inherited runner he stranded. Yet, stranding runners would have to be one of the primary skill sets sought after in RP prospects. I suppose this is somewhat encapsulated in H/9, but, if you subscribe to the theory of "clutchness," there's a difference between allowing hits from the windup with the bases empty and being called in to prevent hits with ducks on the pond, immediately pitching from the stretch and monitoring leads from runners.

Edit: I answered my own question. FanGraphs uses LOB% as this measure, taken not from the actual runners left on according to box scores, but relating it to hit and walk rates as I figured. Peterson sits in around 83% for his young professional career.

I believe what you are looking for is strand rate.

He earned the first win of his professional career last Saturday against the West Michigan Whitecaps, pitching the final 2.1 innings of a 12 inning showdown. He struck out 3, walked none, and allowed 1 hit.

On Thursday, his line was identical (2.1 IP, 8 batters, 3 Ks, 0 BB, 1 H), but pitched in innings 6.2-8 instead.

It's certainly good to see these kind of performances, especially for back to back outings that are tied for the longest of his season (by outs).

Peterson only pitched one inning during the last week. He allowed 1 hit and struck out two, pitching in the ninth inning in a non-save situation. He currently boasts a 0.84 ERA and a 0.938 WHIP. With a BAbip of .348, but a Opposing AVG of .205, his ability to strike out opposing batters (Currently striking out 39% of all batters faced) may be outweighing a lack of "luck" when it comes to balls in play (if "standard" BAbip is assumed to be in the .290 to .300 range).

Peterson earned two more saves since his last appearance. In both instances, he pitched the final inning, not allowing a run. On May 1, he allowed a hit and struck out two, and on May 3, he did not allow a baserunner, striking out 1.

As of this post, Peterson has seen 48 batters, striking out 19, walking 2, and allowing 9 hits - all singles. He has recorded a WHIP of 0.868 and an ERA of 0.71 on 12.2 innings.

Based on my biased opinion, I think that Peterson could be due for a callup to Fort Myers by midseason, even if this dominance falters slightly. He put in time in Elizabethton, and has shown that he can make the batters of the Midwest League miss. He was drafted out of college, so he is admittedly a little old for the level. However, I understand that college draftee + good numbers does not always warrant promotion. We saw that with Walker in the Midwest League too. Only time will tell.

Peterson has had two appearances since moving up to the FSL.
On the 6th, he allowed a hit and a walk, striking out three in the eighth inning of a Miracle win over Bradenton.
On the 9th, he struck out two and allowed one hit, pitching the seventh and eighth innings of a Miracle loss to Jupiter.

Season ERA down to 0.54, K/9 at 13.8, and WHIP at 1.000 on 15.2 IP.

During the last week, Peterson has had two more relief appearances. On the 13th he pitched a scoreless final inning at Brevard County, allowing a hit and a walk, but getting help from a double play ball (his first of the season). It was also his first appearance without a strikeout.
In his most recent appearance, he gave up his second run of the year in two innings of relief against the Cubs. He struck out three, walked one, and allowed a double.

So far he has seen a walk rate increase, though his other numbers have stayed close to where they were in the MWL. Too early to say too much, but he seems to be handling the new level pretty well.

Another post, another pair of appearances for Peterson.
His eighth-inning against the Blue Jays back on the 21st was the second appearance all year without a strikeout. He induced two pop-ups and a groundout.

On the 27th he finished the game against the Clearwater Threshers, pitching the ninth in a non-save situation. He allowed a groundball hit and stuck out 1, getting two flyouts end the inning.

Through 8 innings at Fort Myers, batters are hitting a measly .179 off him.

Earlier this week, Peterson pitched the fifth and sixth innings of a game against the Tampa Yankees. He allowed 1 hit, faced 7 batters, and struck out 5 of them, the most he has struck out in any game this season. His K/9 is up to 12.6 at A+, best on the team (Berrios is second at 10.4). At 22, he is also the third youngest pitcher at Ft. Myers (Berrios and Gilbert are 20 and 21, respectively).

For players with >20 IP on the year, Peterson is near the top in many organizational categories (using combined CR and FM stats): 1st in K/9 and K/BB, 2nd to Oliveros in ERA, 3rd to Achter and Pino in WHIP.

Followers of the Twins affiliates shouldn't sleep on Peterson; a 13th-round reliever isn't going to be the most heralded prospect, but he has kept up good numbers in all three levels he's pitched. For comparison, he's putting up slightly better numbers in nearly all categories (ERA, WHIP, H/9, K/9, K/BB, BB/9) than Tonkin, who played at both Beloit and Ft. Myers in his age-22 season. Granted I'm looking at 60 IP of data for Tonkin that year and only 20 IP for Peterson.

Since my last post, Peterson has had 3 more appearances.
He pitched scoreless 7th and 8th innings against the Lakeland Flying Tigers, allowing 1 hit and striking out 1. He was credited with the win, his first at Ft. Myers.

In a game at Jupiter, he ran into the first real trouble he's had at the A+ level. The starter pitched to one batter in the 8th, giving up a single. Peterson came on and got a groundout, but the following batter singled up the middle to score the inherited runner from second. The next batter doubled, plating the runner from 1st, at which point Peterson was pulled. Gruver relieved Peterson, eventually allowing Peterson's runner to score. All said, Peterson allowed 2 ER and got one ground-ball out.

Yesterday, Peterson pitched one and a third innings of extra baseball against Charlotte. The good: all four outs were strikeouts. The bad: Peterson allowed 3 hits (one was an RBI triple) and walked one, allowing two earned runs and being charged with his first loss of 2014.

It was a tough pair of outings for Peterson as his ER total on the year (6) is now 3 times what it was going into the game against Jupiter (2). On the luck-based front, his BAbip over the last 2 games is .833 ... Basically, there were two outcomes for batters in the two games, hit or strikeout (with the exception of one batter who walked and the other who grounded out). On the season, Peterson should be due to see some more batted balls find his fielders as his total BAbip sits at .356. Then again, I don't know if BAbip stays somewhat elevated in the minors due to potentially lower-quality fielding...

Peterson was back to his usual performance against Bradenton earlier this week. He pitched the 7th inning, facing only 3 batters. He got one groundout and struck out two.

His Ft. Myers ERA sits at 3.07, and his WHIP is 1.091. His SO/W is 5.25. For the season as a whole, he's 1.98, 0.988, and 6.67 for ERA, WHIP, and SO/W.

After getting back on track against Bradenton, Peterson has pitched 5 scoreless innings. He struck out two in two innings of work at St. Lucie, and struck out 3 in the final two innings of a non-save situation against Charlotte. Finally, he was called in for the save in yesterday's home game against St. Lucie. He struck out 1 and got two flyball outs to earn his first FSL save (he had earned 3 in the MWL).

I'm sure that everyone has seen it on the frontpage, but Seth has a great leaderboard for midseason statistics among minor league pitchers (http://twinsdaily.com/content.php/3159-Twins-Minor-League-Leader-Board-(Pitchers)). Peterson is top-ranked in almost all relief pitcher categories.

In two of Peterson's last three outings, he has pitched the ninth inning of non-save situations. On both occasions, he struck out two. However, he walked two yesterday in the ninth. Though he escaped unscathed, it was the first time he has allowed multiple walks in an appearance so far this season.

In a July 3rd game, Peterson pitched one and two-thirds innings of relief. He got the last out of the 6th after Tomshaw exited, stranding two inherited runners. He allowed a single and a double in the 7th for an earned run. Dougie kept him in for the one out of the 8th before bringing in Melotakis to get the final two outs of the inning.

Peterson has only pitched twice in the last 10 days.
In a game against the Palm Beach Cardinals he relieved Steve Gruver who had one runner on base with one out in the eighth. He allowed a double and a single, scoring the inherited runner and giving up an earned run of his own. He got out of the inning two strikeouts later.

Against Dunedin, he struckout two, allowed a walk, got a popout to complete the eighth inning.
