One possibility is placing outfielder Kyle Blanks on the 15-day disabled list after he reaggravated a right foot injury while rounding first base after a two-run homer in Friday's 9-5 win over Florida. Another would be optioning outfielder Drew Macias, who has been recalled on five separate occasions this year.
San Diego had a hole in its starting rotation after optioning Cesar Carrillo, who gave up 15 earned runs in 10 1/3 total innings, on Monday.
LeBlanc, who was officially announced the starter after the Friday's win, is 0-1 and has given up seven runs in 4 1/3 innings (a 14.54 ERA) spanning two starts. Pitching mostly out of Triple-A Portland this year, the 25-year-old went 4-9 with a 3.87 ERA -- striking out 95 batters while walking 31 -- in 24 games (20 starts).
LeBlanc, a second-round Draft pick by the Padres in 2006, will be making his eighth career appearance and seventh start while facing the Marlins for the first time. As a September call-up last year, he went 1-3 with an 8.02 ERA.
