Walker slugged two doubles and collected an RBI on the night and has 17 doubles and 54 RBIs to go along with his Southern League-leading 17 home runs this year.
Sano, who missed all of last season after undergoing Tommy John surgery, is not expected to be too far behind Buxton, who scored the game-winning run in his Major League debut Sunday against Texas. The Lookouts third baseman has 12 homers on the season and has steadily improved his .257/.358/.505 line since opening day.
More standout performances from Top 100 prospects on Monday
• Red Sox No. 1 prospect (No. 7 overall) Yoan Moncada had a productive day for Class A Greenville, crossing the plate three different times while going 1-for-3 with a three-run double. The Drive defeated Rome, 9-3, as the Cuban second baseman upped his season RBI total from seven to 10. Moncada got a late start this year, debuting on May 18 after suffering a shoulder strain during extended Spring Training.
• Indians No. 2 prospect (No. 46 overall) Clint Frazier smacked a solo homer as part of a 1-for-4 day for Class A Advanced Lynchburg. The Hillcat has homered seven times this year, collecting 35 RBIs along the way. Monday's shot was Frazier's first since he launched two in one game on May 30.
Other notable performances from around the Minor Leagues
• Cardinals No. 12 prospect Luke Weaver was nearly perfect for Class A Advanced Palm Beach, ceding a hit and two walks while striking out five in six innings of work. The win was his first of the season, but that statistic is not a good indication of the way he's pitched this year. His ERA is 2.63 and the right-hander has not given up more than three earned runs in any of his six starts for the Cardinals. "It all came together as a whole," he told MiLB.com after his great outing on Monday. "Coming off of this, I expect to just keep that rolling and take the same mentality into the next start."
• Cardinals No. 17 prospect Patrick Wisdom hit a grand slam as part of a two-home-run game to give Double-A Springfield a 10th-inning win. "Everybody was juiced when I got back to the dugout," he told MiLB.com. "High fives everywhere. Emotions were running pretty high." The No. 52 overall pick in 2012 has hit five homers and collected 27 RBIs this season. He's batting .254/.318/.430 with eight doubles and a triple and is on pace to blow by most of his numbers from his 2014 stint in Springfield.
• D-backs No. 16 prospect Stryker Trahan broke out of a slump for Class A Advanced Visalia, hitting a two-run homer that ended an 0-for-12 streak. The slugger hit a homer in his first Class A Advanced at-bat on June 11, but had no luck in the three games before Monday's contest. He now has two dingers and three RBIs at this level and has a while before he catches the 11 homers and 38 RBIs that he racked up at Class A Kane County.
• Marlins No. 11 prospect Kendry Flores and Rangers No. 19 prospect Jared Eickhoff squared off against each other on Monday night. Starting his first game for Triple-A New Orleans this year, Flores gave up three hits and struck out six in five shutout innings. Eickhoff was just as good for Round Rock, giving up four hits and striking out six in six shutout innings. Neither starter got the decision, as the game remained scoreless until Michael Choice hit a walk-off homer for Round Rock in the 13th inning.
• Rangers No. 10 prospect Luis Ortiz piled up a career-high nine strikeouts for Class A Advanced Hickory. He went five innings in the Crawdads' 4-1 win over Savannah, giving up three hits and one run while walking one. The most strikeouts Ortiz had notched in a game this season was six on April 23 and he surpassed that early in Monday's contest. The right-hander won his second straight and is 4-1 with a 1.72 ERA this year.
• Royals No. 24 prospect Eric Skoglund won his third straight while returning to elite form for Class A Advanced Wilmington. The 6-foot-7 southpaw had given up at least three earned runs in three straight games entering Monday, but he only surrendered four hits and one unearned run in seven innings of work. Meanwhile, he recorded eight strikeouts -- his highest total since May 23 -- against no walks and moved his season record to 6-2 with a 2.77 ERA.
