How is your team doing so far this year? Do you need some help from the pitching side? Here are some guys that you could trade for or at least one you could pick off the waiver wire before he returns.
Danny Salazar's skills have been superior this year. While he is owned, owners in keeper leagues should target him as a future ace. His 11.8 K/9 with a 3.50 ERA is a good start, but his 3.34 FIP shows that there could be some upside during 2015. If he can maintain his 46% GB rate then he can slowly start to limit the HR ball (18% HR/FB), especially when he faces lefties. He is worth trading for, and hopefully he will continue to throw strikes in 2015.
Rubby De La Rosa can be picked up on some waiver wires. His 5.09 ERA may have some owners shaking their heads, but his 8.7 K/9 and his 48% GB rate should push his year-end ERA closer to 4.00. He owns a 4.36 FIP this year, and he his throwing more First-pitch strikes (64% this year). HIs ability to keep the ball on the ground and throw strikes will lead to consistent starts. He faces the Dodgers tonight, but this may provide an opportunity to buy him at a lower cost. If he is on the waiver wire in your league, pick him up and slot him in the back of your rotation.
Kevin Gausman is working his way back to Baltimore, and it looks like he will have a shot at the rotation. While he maintained a 9.8 K/9 in a small sample size in relief, he should be able to maintain at least a 8.0 K/9 as a SP. Gausman could throw 7 QS out of 12 GS for your team the rest of the season. Monitor his progress with his shoulder, and check to see if his health holds up. He only needs playing time to show that his skills are worth a #4/5 SP role.
