San Diego's Tyson Ross hopes a flip of the calendar will also turn his luck.
But with Reds ace Johnny Cueto on the mound, that seems like a tough task.
Ross went 0-4 in June despite posting a 3.94 ERA and throwing into the sixth inning in each of his five starts. The Padres, who rank last in the Majors in runs, batting average and slugging percentage, scored just one run while Ross was on the mound last month -- and it was Ross who drove it in with a sacrifice fly.
In his last start Friday against the D-backs, Ross went seven innings, allowing two runs on five hits while striking out seven. He has allowed more than two earned runs in just three of his last 11 starts.
"I could go back and watch film and look at the pitches I need to execute," Ross said. "I've got to go out there and make pitches and that's the bottom line."
In his career against Cincinnati, Ross is 2-0 with a 1.13 ERA in 16 innings across three appearances.
Cueto, meanwhile, enters Wednesday's game as the National League Cy Young Award favorite after posting an 8-5 record and a league-leading 1.88 ERA through 17 starts. Cueto's ERA has not been above 2.00 since April 11, his third start of the season.
In his last start, Cueto was two outs away from a complete game but was pulled after giving up two runs on four hits during a 6-2 win at San Francisco on Friday. In his last two starts, he has pitched 16 1/3 innings while crafting a 1.65 ERA and 0.86 WHIP.
Cueto has posted quality starts in 15 of his 17 outings.
Reds: Leake getting offensive
With the club carrying 13 pitchers, the bench is thin, consisting of four position players. The short-handed bench could mean more offensive opportunities, as both a pinch-hitter and pinch-runner, for pitcher Mike Leake.
"There's more than discussion or thought, he is a usable piece and he knows that," manager Bryan Price said. "Typically we don't want to use him the day before he starts, I'd like him to maintain his routine, which is being in here and doing his charting and preparing for his start."
Price, however, did say Leake would be available on other days.
"No doubt about it," Price said. "He's an early-burn pinch-hitter, a guy that can pinch-run, he can get a bunt down for us if we don't want to burn [Ramon Santiago] or someone else early in the game."
Leake is a career .236 hitter and starred as both a hitter and pitcher at Arizona State. In three years as a Sun Devil, Leake hit .299.
Padres: How about Hahn?
Right-hander Jesse Hahn put together a historic month on the mound, as his four wins in June were tied for the most in a single month by a Padres rookie pitcher.
Hahn limited the opposition to a .190 batting average in June, the second-lowest opponents average of any qualifying Padres rookie pitcher in any month in franchise history, behind only the .188 mark put up by Eric Nolte in August 1987.
Hahn's 1.95 ERA last month is the 10th-lowest by any rookie pitcher in any month in franchise history (minimum of 25 innings) and the lowest since Justin Germano posted a 1.08 ERA in May 2007.
Hahn's 36 strikeouts through five career games are the most by any Padres pitcher, breaking the record (32) set by Andy Benes in 1989.
"We're watching this kid develop and liking what we're seeing," said Padres manager Bud Black. "We've been impressed by his work so far."
• The Padres are still trying to figure out if they'll need to send shortstop Everth Cabrera to the disabled list after he suffered a strained left hamstring late in Monday's victory over the Reds. Alexi Amarista got the start at shortstop Tuesday.
The Padres won't make a decision until Friday on Cabrera, meaning they'll be short-handed in terms of position players in Wednesday's series finale.
• The Reds have scored first in 15 of their last 20 games. They are 14-6 in those games.
