This is what they were waiting for
Brett Wallace, 3B/1B, Athletics (Triple-A Sacramento)
Sunday's stats: 4-for-5, HR (3), 2 R, RBI
When the A's traded Matt Holliday to the Cardinals, Wallace was the big prize in return, but he hadn't done much since arriving in California's capital. Not that he's been bad, mind you, just that he's been simply all right. Sunday's big game brings his averages up to .284/.347/.443 (average/on-base/slugging), but there are still concerns, in particular his range at third base and a tendency to destroy lefties and struggle a bit against right-handers.
Meanwhile, in other trade-deadline news
Mauricio Robles, LHP, Mariners (High-A High Desert)
Sunday's stats: 7 IP, 1 H, 0 R, 3 BB, 9 K
Acquired from Detroit in the Jarrod Washburn swap, Robles faced a difficult assignment to High Desert following the deal, but he delivered his best outing as a Mariner on Sunday. Despite a skinny 5-foot-10 frame, his lightning-quick arm allows him to get into the mid-90s with his fastball, which has led to 124 whiffs in 104 2/3 innings, but his command, control, and secondary offerings lag behind. Still, this kind of velocity is hard to find in a lefty, and he'll get plenty of chances to figure it out.
