Danny Santana was called up because the Twins were just about out of choices for position players. He didn't play every day at first, but did start to hit right away. He hit enough to stay, then to play every day as the leadoff hitter and now almost certainly will make the Twins as their leadoff hitter in 2015. Santana is hitting .316 with an OPS of .822, fine numbers. Looking more deeply at his splits, he has hit better as a lefty (.851 OPS), hit well in almost every situation, and shown enough pop and speed to excite the fan base. If there are concerns, they would be about contact and BB/K ratio. Danny has struck out 78 times in slightly over half a season's at bat. He has drawn only 17 walks. I don't have his BABIP at my fingertips, but it has to be pretty high, which is fitting for a switch hitter with excellent speed, but he would probably be categorized as "lucky" in his young career. As mentioned previously, Santana has an OPS about 100 points higher as a left handed hitter. His OPS from the right side is a still-very-acceptable .752. He joins Kennys Vargas as a Twins switch hitter who fares better against right-handed pitching. Santana is 23 and has put up a very fine rookie season. What is his major league future and will he be the Twins regular shortstop for years to come?
