Arizona won 4-3 last night but that was the D-Backs 2ns win in it's last 9 games. Right-handers Luis Castillo (6-7, 3.02 ERA) of the Mariners and Merrill Kelly (9-4, 3.12) of the Diamondbacks will start for their respective teams Sunday. On Monday, Castillo gave up two runs and four hits in seven innings. He struck out nine and walked two, and does really well on the road in general with a 1.17 WHIP, so we roll with Seattle as Arizona has come out of the gate slow after the All-Star Break, and if there is any time to fade Merrill Kelly, it's during day games as he has a 4.84 ERA under the sun.
