Great pick up for the A's. He still has a bit of gas in the tank and going to the cavernous coliseum should only help him out. What you A's fans will really like about him is if you can find the magic and make a playoff run again;
In six career post season starts
15 Game 3 ALDS: 6.1 IP, 1 ER, 4 SO
'15 Game 1 ALCS: 5.1 IP, 3 ER, 6 SO
'15 Game 5 ALCS: 7.2 IP, 1 ER, 5 SO
'16 Game 1 ALDS: 8.1 IP, 1 ER, 6 SO
'16 Game 1 ALCS: 8 IP, 2 ER, 6 SO
'16 Game 5 ALCS: 6 IP, 2 ER, 7 SO
Total: 3-3, 2.64 ERA, 30 so.
Dude was absolute money in crunch time. Given the A's ability to pick any scrap heap off the pile and turn it into a competent starter i think this will be a great move.
