Outlook Spencer Horwitz

Favorable Road Matchups Make Horwitz a Must-Start This Week

Spencer Horwitz has cooled down slightly over the last seven days with a .238 average, but he remains a crucial contributor for the 36-36 Pirates, who sit fourth in the NL Central. Serving as Pittsburgh's everyday first baseman, his strong .290 batting average and six home runs over the last 30 days have kept him highly relevant in fantasy circles. With key lineup pieces like Oneil Cruz currently sidelined, Horwitz's security in the heart of the order is highly stable.

On the year, Horwitz is slashing .281/.388/.452 with nine home runs, pacing well ahead of our season projection of a .256 average and nine total homers. His elite plate discipline and high on-base skills are backed by a strong career track record of drawing walks, proving his OBP floor is entirely sustainable. While his recent power surge might experience minor regression, he remains an excellent asset for managers needing batting average and run production.

The Pirates embark on a highly favorable six-game road trip this week, starting with three games in Oakland before heading to hitter-friendly Coors Field to face Colorado. Horwitz will face several vulnerable pitchers, including Jack Perkins and Kyle Freeland, who both carry ERAs well over 6.00. Our weekly models project him to hit near .300 with multiple runs and runs batted in, making him an easy lineup choice. Verdict: Start.

Outlook Yainer Diaz

Yainer Diaz nearing return from oblique injury, but remains a sit for this week

Astros catcher Yainer Diaz remains sidelined with a left oblique strain that has kept him out since early May, yielding no recent game action over the last 30 days. He is reportedly nearing a mid-June return, which would provide a major boost to a fourth-place Houston squad (33-40) currently starting Christian Vázquez behind the plate.

Before the injury, Diaz was batting .248 with two home runs through 26 games, a slight step back from his stellar .299 mark in 2024. However, our projection expects a strong rebound to a .270 average with 14 home runs over 492 at-bats, cementing his status as a high-impact offensive catcher once healthy.

Houston has six games scheduled this week against the Tigers and Guardians, featuring matchups with tough starters like Casey Mize (2.27 ERA) and Gavin Williams (3.32 ERA). Because Diaz is still finalizing his return from the injured list and not yet active on the depth chart, fantasy managers should keep him benched for now. Verdict: Sit.
