It's been an interesting season for Trevor Cahill, who was once viewed as one of the best young pitchers in the game during his time with the Oakland Athletics.
After struggling to a 9.17 ERA through his first four starts, he was moved to the bullpen, and all told, he was 1-6 with a 5.66 ERA in 19 appearances before being designated for assignment at the beginning of June.
The 26-year-old cleared waivers and joined the team for seven minor league starts before rejoining the big league club and the starting rotation on July 18.
He's gone 2-2 with a 3.43 ERA in seven starts since returning, including five consecutive quality starts.
"Anytime I feel like I can throw the ball somewhat where I want to, I feel a lot more confident," Cahill told Nick Piecoro of The Arizona Republic. "It's tough when you're throwing and your stuff is kind of going all over the place. You start competing against yourself more so than the other team. Just the fact that I feel like I can locate two or three of my pitches definitely helps a lot."
Digging deeper, he has a 2.71 FIP over the last 30 days, which is better than that of Jon Lester (2.76) and Felix Hernandez (2.91) among many others, according to a tweet from Beyond the Box Score.
Cahill was one of a handful of Diamondbacks players placed on waivers, according to a tweet from Ken Rosenthal of Fox Sports, and if he clears, a team like the Los Angeles Angels could certainly have some interest.
He is still owed $12 million next season, with a pair of option years that will cost a combined $800,000 to buy out, so salary could be a sticking point in any deal. If the Diamondbacks are willing to eat a decent chunk of that salary, though, he could be a nice pickup.
