Whole team pitches in for six-run fourth frame

PEORIA, Ariz. -- The Padres parlayed five consecutive hits into a six-run fourth inning Tuesday on the way to a 7-5 Cactus League victory against the Reds at the Peoria Sports Complex.

Yasmani Grandal, Travis Buck, Alexi Amarista and Everth Cabrera each had run-scoring singles during the big inning against Reds Minor League pitcher Pedro Villarreal, while Kyle Blanks and Chase Headley added sacrifice flys.

San Diego starting pitcher Anthony Bass tossed two shutout innings and his Cincinnati counterpart, Homer Bailey, threw 15 pitches in one scoreless frame. Both were gone before the Padres' outburst in the fourth.

"Short and sweet," said Bailey, who threw seven of his 15 pitches for strikes. "That's why I only threw one inning -- we have that extra week of games. You can't just sit idle, and throwing bullpens or live BP after a while gets pretty monotonous. I kind of like it to get to go out there for one inning. You can kind of go through all of your pregame routine a little bit and do all the things in bullpen you want to do before a game. And then you get back in the competition pretty quick."

Bailey walked one and struck out one. Bass allowed one hit in a 16-pitch effort.

"I wanted to establish the fastball and work it in and out, up and down," said Bass, who is in competition for a spot in the rotation.

The Reds (1-4) scored two runs in the third inning on an RBI triple by right fielder Chris Heisey and an RBI single through a drawn-in infield by leadoff hitter Shin-Soo Choo.

Trailing, 2-0, the Padres (3-2) sent 11 batters to the plate in the fourth inning.

Jedd Gyorko added his third homer of the spring in the eighth inning for the Padres. San Diego center fielder Cameron Maybin had two hits, and Headley reached base twice.

Up next for Padres:: The Padres will have their first split-squad games of the season Wednesday, both at 12:05 p.m. PT. Sean O'Sullivan will get the start and is scheduled for three innings in a game against the Rockies in Peoria. O'Sullivan tossed two scoreless innings in his Cactus League debut against the Mariners last week. He's a non-roster invitee with an outside shot of making the team. Eric Stults makes his first start of the spring in a game against the A's in Phoenix. He's likely set to go two innings, as well, and has a good shot to make the Padres' starting rotation to open the season.
