Monday night's game at Petco Park was a tale of two pitchers.

Mat Latos got off to an impressive start in his 2011 debut, striking out five without allowing a hit over his first three innings.

But over his next two innings, Latos gave up three runs on a pair of two-out homers by Cincinnati's Jonny Gomes (solo) and Chris Heisey (two-run).

Meanwhile, the Reds' Edinson Volquez again struggled at the start of his start, giving up two runs in the first inning. But he got stronger as the game progressed, retiring 15 of the last 18 hitters he faced.

The result was a 3-2 Reds win — largely because Padres again failed to get runners home from second with less than two outs in their final two innings.

Latos opened the season on the disabled list with bursitis in his valuable right shoulder after an unsettling spring that saw him battle his command and emotions.

But his pitches Monday night had considerable movement.

The velocity on his fastball was steadily between 93-95 mph and topped out at 97. His slider registered 88-89 and his changeup was around 83.

His first four strikeout victims — 2010 National League MVP Joey Votto, Gomes, Jay Bruce and Paul Janish — all took called third strikes.
