Cardinals Farm Report: Pitching Prospects Finish Strong Before All-Star Break

Cardinals Farm Report: Pitching Prospects Finish Strong Before All-Star Break originally appeared on Athlon Sports.

In each of their final starts before the MLB All-Star Break, three pitching prospects in the St. Louis Cardinals organization had big performances on the bump.

Here's a look at each of their solid outings, along with an update on perhaps the organization's most exciting prospect:

Tekoah Roby, Memphis Redbirds (Triple-A)

Roby, the Cardinals' No. 10 prospect, turned in 5 2/3 innings of shutout work for the Redbirds on July 10, striking out six and only walking one batter.

The 23-year-old righty has been dominant on the mound over his last four starts, carrying an ERA of 0.86 and a 1.10 WHIP with 21 strikeouts in 21 innings pitched to lower his season ERA to 3.10 with 87 strikeouts in 78 1/3 innings of work.

Quinn Mathews, Memphis Redbirds (Triple-A)

Like Roby, Mathews put up four shutout innings for the Redbirds last week. The team's No. 2 prospect struck out five and walked two in the outing, bouncing back from a rough start on July 5, in which he allowed four runs on two hits and four walks in 4 2/3 innings pitched.

Dating back to his May 19 return from IL, the 24-year-old has had a tough time finding consistency on the bump, following a good start with a bad start and vice versa. With a week off for All-Star festivities, the southpaw could use this time to mentally regroup and build off the way he finished his last start.

Ixan Henderson, Springfield Cardinals (Double-A)

Henderson, the Cardinals' No. 25 prospect, put together a quality start before the break, turning in six shutout innings and allowing just four hits and one walk while striking out seven batters.

The 23-year-old lefty is quietly putting together a fantastic year, currently carrying a 2.36 ERA and 1.18 WHIP with 88 strikeouts in 80 innings pitched across 15 starts.

The former eighth round pick holds a career ERA of 2.30 in 41 minor league appearances dating back to 2023.

JJ Wetherholt impresses in first week with Triple-A Memphis:

Wetherholt, the team's top prospect, was promoted to Triple-A on July 7 and has already been making waves at the next level.

In three games, the 22-year-old has hit a double, triple and home run, scored four times, driven in two and walked once. He's slashing .364/.417/.909/1.326 in his first 11 Triple-A at bats.

After finishing the week with Memphis, Wetherholt suited up for the MLB All-Star Futures Game and led off the bottom of the first with a double.
