Jason Hammel is not taking to Oakland well.
The veteran righty was pitching at an All-Star level for the Cubs before being dealt to the A's on July 4 with Jeff Samardzija for top prospect Addison Russell.
But since then? Eh, not so much.
Hammel got absolutely rocked by a Houston Astros lineup that featured three starters hitting below .200 Wednesday afternoon and his Cubs-A's splits are eye-popping:
With Cubs (17 starts): 8-5, 108.2 IP, 88 H, 36 ER, 10 HR, 23 BB, 104 K, 2.98 ERA, 1.02 WHIP
With A's (4 starts): 0-4, 17 IP, 26 H, 18 ER, 5 HR, 12 K, 9.53 ERA, 2.12 WHIP
So, in 91.2 fewer innings with the A's, Hammel has already surrendered 50 percent of the earned runs and homers that he gave up with the Cubs.
Hammel, 31, was 49-53 with a 4.67 ERA and 1.42 WHIP in his career prior to 2014, so his first half with the Cubs may have been a bit over his head. But the struggles in Oakland are really uncharacteristic.
Even if Hammel turns things around in a hurry, Theo Epstein's front office did well to sell high on the veteran righty, who inked a one-year deal worth $6 million in the offseason.
Meanwhile, Samardzija is looking like a bonafide ace still with the A's, going 2-1 with a 3.19 ERA and 0.82 WHIP in his first five Oakland starts.
