Drew Robinson didn't hit his first home run this season until May 23, while playing in his 36th game for Triple-A Round Rock. Since then, however, opposing pitchers have had trouble keeping him in the park.
The Rangers' No. 23 prospect hit a pair of solo shots on Tuesday night, including his second leadoff homer in as many days. He also hit a double and scored three runs before finishing 3-for-5, though it wasn't enough to prevent the Express from falling to Colorado Springs, 12-8.
With the multihomer performance, Robinson has now hit all six of his home runs during his last nine games. The 25-year-old utility man has hit .405, with 12 extra-base hits (of his 15 hits) and 13 RBIs, in that stretch to lift his overall slash line from .243/.368/.346 to .277/.384/.509.
A fourth-round Draft pick in 2010, Robinson posted back-to-back 20-homer seasons (2015-16) en route to cracking the Rangers' Opening Day roster this year -- the first of his two stints in the Majors this season. He made his big league debut on April 5, going 0-for-2 as the Rangers' designated hitter.
The rest of the best performances from top prospects Tuesday
• No. 16 overall prospectWilly Adames (Rays' No. 1) extended his hitting streak to seven games and his RBI streak to five games as he connected on his second home run in four games for Triple-A Durham. It was the fourth homer in 52 games for the 21-year-old shortstop, who's batting .385 with nine RBIs and five walks during his current hitting streak.

• Brewers No. 7 prospect Lucas Erceg went a combined 3-for-6 with four RBIs to pace Class A Advanced Carolina in a doubleheader sweep of Winston-Salem.

The 22-year-old third baseman has swung a hot bat over his last three games, going 7-for-11 with seven RBIs.

• Reds No. 8 prospectSal Romano struck out a season-high eight batters over five scoreless innings for Triple-A Louisville in his first start back from the disabled list. The 23-year-old righty threw 56 of his 82 pitches for strikes, as he allowed five hits, walked two and generated five ground-ball outs. He'd been on the disabled list since April 27 with right shoulder inflammation.
• White Sox No. 11 prospectDane Dunning was a tough-luck loser despite a dominant outing for Class A Advanced Winston-Salem. Starting game two of a double dip against Carolina, the 22-year-old righty recorded 11 of his 15 outs via the strikeout over five innings, within which he allowed four unearned runs on four hits. It was his best performance in six starts since being promoted to the Carolina League.
• White Sox No. 19 prospect Bernardo Flores scattered five hits over six scoreless frames and recorded a season-high seven strikeouts in a no-decision for Class A Kannapolis against Lakewood. The 21-year-old lefty has pitched well across his last three starts, posting a 1.06 ERA with a 16-to-2 strikeout-to-walk ratio in 17 innings. Kannapolis ultimately won the contest in 16 innings, 2-1.
