Monday's meeting between the Rockies and Padres features one starter slowly approaching the end of the line this season, and another with something still left to prove.
Padres right-hander Jesse Hahn has been a revelation this season, registering a 2.28 ERA across his first 59 1/3 Major League innings. Yet considering he only threw 69 innings last season and tossed 40 1/3 before making the Majors this year, his time to be shut down could soon be around the corner.
"With Jesse, there will be a finish line, but we haven't put a set finish line on his innings, though we're discussing it," said Padres manager Bud Black.
In his last start, Hahn allowed three runs on four hits across 5 2/3 innings against the Twins. All three runs came on one swing -- a three-run homer from Kennys Vargas on a hanging curveball. That damage was enough to hand Hahn the first road loss of his short career.
In the other corner of the series opener is Rockies right-hander Jordan Lyles. Lyles was off to a fine start to his Rockies career before fracturing his non-pitching hand on June 4. But instead of being discouraged by the setback, he used the time off to focus on learning a new pitch: the split-changeup.
In his first start back last Wednesday, Lyles threw the changeup 20 times in tossing six innings of four-run ball in a win over the Cubs.
He already feels it's the perfect offspeed complement to his fastball and cutter, and he's hoping the pitch will help him end the season on a high note after missing two months.
"I'm excited about that pitch," Lyles said. "I think it's going to do wonders for me and for my career down the road."
Rockies: CarGo's nagging knee tendinitis lands him on the DL
Outfielder Carlos Gonzalez was placed on the 15-day disabled list Sunday as the Rockies look to give him a break from his left knee tendinitis.
It's the second time Gonzalez has landed on the DL this season, with the first being a stint that cost him a little over a month thanks to a benign tumor in his left index finger. He's also been dealing with a right ankle sprain for the past two weeks, and the accumulation of everything has resulted in some unflattering stats.
Since returning from finger surgery on July 11, has hit .188 (12-for-64) with 25 strikeouts to five walks.
Padres: Getting Tommy back
The Padres hope to get first baseman/outfielder Tommy Medica back in the starting lineup on Monday against the Rockies.
Medica was hit in the back of the helmet in the eighth inning of Saturday's 2-1 victory over the Pirates.
He was not in the starting lineup of Sunday's 8-2 win over the Bucs, but he did have a pinch-hit double in the eighth inning.
The Padres could certainly use Medica's bat. Since the All-Star Break, he's hitting .396 (19-for-48), which ranks near the top of the National League.
• Rockies left-hander Brett Anderson will visit a spinal surgeon Monday about the bulging disk in his lower back that flared up last Tuesday. He's unlikely to return this season.
• Rockies shortstop Troy Tulowitzki was sent back to Denver Sunday to receive additional opinions on his ailing left hip flexor.
• Padres shortstop Everth Cabrera was scratched from Sunday's lineup with a left hamstring cramp.
