Philadelphia Phillies starting pitcher Aaron Nola improved to 12-6 in Tuesday's 5-0 win over the Astros. Nola turned in another great start, pitching seven innings with four hits, one walk, and six strikeouts. The 31-year-old has followed his recent strong-season/down-season trend, compiling a 3.30 ERA, an 8.28 K/9 rate, and a 2.27 BB/9 rate in 27 starts (17 quality starts) and 166 1/3 IP this season. He will face a tougher matchup against the division-rival Braves in his next start, but fantasy managers should feel confident in starting him in any matchup down the stretch based on his season performance.

Washington Nationals starting pitcher Patrick Corbin improved to 4-12 on Tuesday, pitching a gem against a tough Yankees lineup in a 4-2 win. Corbin pitched six scoreless innings, allowing just two hits and two walks with six strikeouts. The 35-year-old veteran has strung together two consecutive quality starts, but his overall season numbers are still poor with a 5.50 ERA, a 6.90 K/9 rate, and a 2.93 BB/9 rate in 27 starts and 147 1/3 IP. His next start will be a much more favorable matchup at the Marlins. Even so, fantasy managers may not want to trust Corbin so close to fantasy playoffs.

Colorado Rockies shortstop Ezequiel Tovar (hernia) had a great game back in the lineup for Tuesday's 9-8 loss to the Marlins. Tovar, who missed Monday's game due to a sports hernia, went 3-for-4 with a double, a solo home run, a two-run HR, four RBI, and a strikeout. The 23-year-old went back-to-back with Charlie Blackmon in the first inning, launching a 456-foot bomb to straightaway center. He victimized Roddery Munoz again in the second inning, lining a fastball into the left-field seats. This performance was encouraging for fantasy managers, for while Tovar's season numbers are fine, he owns a poor .202/.224/.372 slash line in 94 August at-bats.

Oakland Athletics outfielder Lawrence Butler had a nice game at the plate in Tuesday's 5-4 win over the Reds. Butler went 2-for-5 with a single and a two-run home run. The 24-year-old capped off a four-run seventh inning, crushing a Justin Wilson slider into the left-field seats. Butler has shown some encouraging signs throughout the season but has been erratic overall. His July was stellar but his production the rest of the season has been lackluster, culminating in a .246/.304/.462 slash line with 15 HR, 45 runs scored, 45 RBI, and 11 stolen bases in 332 plate appearances.

Oakland Athletics closer Mason Miller made things interesting but came away with his 22nd save of the season in Tuesday's 5-4 win over the Reds. Miller came in to pitch the bottom of the ninth inning up by three. He got the first out on a strikeout, allowed back-to-back singles, and got the second out on an RBI groundout. He then allowed an RBI single and a double but left the tying run stranded at third with another strikeout. This wasn't Miller's finest outing but he has been excellent all season long and hadn't allowed any runs since July 2. The 26-year-old has converted all but two of his save opportunities with a 2.12 ERA, a 14.82 K/9 rate, and a 3.00 BB/9 rate in 51 innings of work.
