Hanson, Garrett among top prospect performers Monday

Two top prospects shined in a wild Triple-A contest in Indianapolis on Monday night. Reds No. 2 prospect Amir Garrett threw seven scoreless innings in Louisville's 5-2 loss to Indianapolis. Garrett, baseball's No. 52 overall prospect, gave up six hits while walking two and fanning five.

He lowered his ERA to 3.24 in nine games (eight starts) for Louisville this season.

With Indianapolis trailing 2-1 in the bottom of the ninth, Pirates No. 14 prospect Alen Hanson hit a walk-off grand slam. Hanson went 3-for-5 on the night, and has hit safely in 14 of his past 15 games.

The rest of the best performances from top prospects on Monday:

Phillies No. 2 prospect and No. 29 overall prospect Mickey Moniak continued his hot start with a 2-for-3 performance for Philadelphia's Gulf Coast League rookie affiliate in a 4-0 win over the GCL Blue Jays. The top overall pick in this year's Draft upped his batting average to .305 after 34 games.

Padres No. 4 prospect and No. 100 overall prospect Josh Naylor went 3-for-4 with two RBIs in Class A Advanced Lake Elsinore's 8-7 win over Inland Empire. Since being traded from the Marlins to the Padres, Naylor is batting .304 with 17 RBIs in 16 games.

Athletics No. 24 prospect Casey Meisner tossed 4 2/3 scoreless innings in relief to pick up the win in Class A Advanced Stockton's 2-1 California League victory over Visalia. The right-hander surrendered just one hit, walked none and struck out six. The performance was a welcome sign for Meisner, who entered the game with a 4.17 ERA.

Blue Jays No. 6 prospect Jon Harris tossed 7 2/3 innings for Class A-Advanced Dunedin on Monday night, giving up one run on three hits while walking one and striking out five in a 4-1 win over Clearwater. The right-hander lowered his ERA to 2.96 since being promoted to Dunedin from Class A Lansing.

Brewers No. 15 prospect Jacob Nottingham hit his ninth home run of the season in a 3-for-5 effort in Double-A Biloxi's 8-3 win over Jackson. He had been 2-for-11 going into the game.

Cubs No. 16 prospect Jake Stinnett turned in a stellar performance for Class A Advanced Myrtle Beach of the Carolina League. The right-hander went seven innings, allowing one run on five hits, walking one and striking out six. He's allowed one earned run or fewer in three of his past four starts.

Dodgers No. 16 prospect Imani Abdullah went five strong innings for Class A Great Lakes, giving up one run on two hits while walking one and striking out three in a 7-1 win over Lansing.

Dodgers No. 30 prospect Trevor Oaks was brilliant in a complete-game victory for Triple-A Oklahoma City over El Paso. The right-hander gave up one run on three hits, striking out 11 without yielding a walk and didn't allow a hit until the seventh inning. In nine starts for Oklahoma City, he's posted a 3.03 ERA.

Mets No. 5 prospect Brandon Nimmo had a big night at the plate, going 4-for-6 with a double in Triple-A Las Vegas' 12-8 loss to New Orleans. With the performance, Nimmo upped his batting average to .341. Over his last three games, the outfielder is batting .500 (8-for-16).

Nationals No. 21 prospect Anderson Franco went 2-for-5 with a home run for Washington's GCL affiliate in an 8-0 win over the GCL Marlins. It was Franco's first home run in exactly one year -- his last round-tripper came on Aug. 15, 2015.

Phillies No. 15 prospect Cole Stobbe had a game to remember for Philadelphia's GCL club, going 2-for-4 with his first professional home run in a 4-0 win over the GCL Blue Jays. Philadelphia's third-round selection in this year's Draft, Stobbe is starting to heat up at the plate, recording a hit in four straight games. The third baseman has raised his batting average from .234 to .259 in that span.

Twins No. 16 prospect Adam Walker hit his International League-leading 24th home run of the season for Triple-A Rochester in a 10-4 win over Buffalo. Walker is looking to lead his league in home runs for the fourth time in his Minor League career. He led the Class A Midwest League with 27 homers in 2013, the Class A-Advanced Florida State League with 25 homers in 2014, and the Double-A Southern League with 31 homers last year.

Twins No. 21 prospect Daniel Palka had a big night, going 2-for-4 with a double and a home run in Rochester's win over Buffalo. Palka is 4-for-7 with two home runs and four RBIs in his last two games, raising his batting average from .250 to .268 in 34 games since being promoted from Double-A Chattanooga.

White Sox No. 27 prospect Corey Zangari hit two homers and drove in three for Rookie-level Great Falls in a 7-6 win over Ogden. It was Zangari's second multi-homer game as a pro, and first this season.
