While Reds right-hander Mat Latos and Padres right-hander Edinson Volquez have faced each other only once during their careers, much more of a connection exists.
On Dec. 17, 2011, Latos was traded to the Reds in exchange for Volquez, Yasmani Grandal, Yonder Alonso and Brad Boxberger.
The pitchers will square off a second time on Tuesday night at Petco Park in the second game of a three-game series. They dueled for seven innings on July 5 last season before a walk-off single in the ninth gave the Padres a 2-1 victory.
Though the Reds have lost four games in a row, Latos takes the hill on quite a roll. He's won three of his last four starts, including an efficient outing against the Dodgers on Thursday, when he allowed just two runs (one earned) on eight hits in 7 2/3 innings to pick up his 10th win of the season.
"I felt pretty good today," Latos said after the start. "All in all, I can't complain. That lineup that they have is a good one. I was able to work the fastball in pretty good."
Volquez is looking for his third straight win after getting a victory against the Brewers on Thursday. Volquez got off to a good start, allowing one run in the first five innings before running into trouble in the sixth. In total, he allowed three runs on six hits over 5 1/3 innings.
With an effective curveball and changeup throughout the game, Volquez struck out five. Over his last 14 starts, the righty has struck out 76 batters in his last 76 1/3 innings.
Padres pitchers have allowed one run in the past 22 innings, an RBI fielder's choice by Cesar Izturis in the fifth inning of a 2-1 win over the Reds on Monday night.
The Padres, who have seven games left in their homestand, have won seven of their last 11 games.
Reds: Choo day to day
Cincinnati center fielder Shin-Soo Choo was out of the starting lineup for Monday's series opener because of a minor left ankle sprain.
Choo pinch-hit for Tony Cingrani in the eighth inning of Sunday's 1-0, 11-inning loss to the Dodgers in Los Angeles and was promptly hit by the pitch. He then stole second base but jammed his ankle with a late slide into the bag.
"It was an awkward slide," Reds manager Dusty Baker said. "I saw him when he got up, he was twisting his ankle. I didn't know how badly he had done it. He is day to day."
Second baseman Brandon Phillips joined Choo on the bench Monday, getting a scheduled day off.
Padres: Maybin close to rehab stint
San Diego center fielder Cameron Maybin continues to progress in his rehab from ligament damage in his left knee and should be ready to begin a rehab stint soon.
"He's moving around like he's getting real close," Padres manager Bud Black said. "Might even be joining that [Triple-A] Tucson team before too long."
Maybin injured his knee after landing on it while attempting to catch a fly ball on June 9, just four games after he returned from a right wrist injury that cost him 45 games.
"I think the key is for him to get back on the field and play the rest of the season healthy," Black said. "How he plays, his legs are a big part of his game and speed, and the wrist is hopefully not a factor."
• The Reds, who scored 36 runs over the first five games of their 11-game West Coast road trip, have scored only three runs over their last 38 innings. They were 0-for-5 with runners in scoring position on Monday and are 1-for-23 in those situations during their four-game losing streak.
• Reds reliever Jonathan Broxton (right elbow) will begin a rehab assignment with Triple-A Louisville on Tuesday. Broxton threw live batting practice to Reds hitters on Saturday in Los Angeles.
• Padres outfielder Carlos Quentin was scratched from the starting lineup for Monday night's series opener with a sore left knee but was preparing to pinch-hit before Chris Denorfia's home run ended the game.
