Andruw Monasterio Is Forcing the Conversation

Andruw Monasterio is slashing .344 with a .441 wOBA over his last 72 plate appearances, and the multi-position eligibility (1B, 2B, 3B, SS) makes him one of the most flexible assets sitting on your waiver wire right now. At 3% rostered, the window to act is still wide open — but it's closing fast, with a +2% ownership spike in the last seven days alone.

WaiverScout Had This One Early

We first flagged Monasterio back on May 16 when he was rostered in 0% of leagues. He bounced between watch and deprioritize classifications through June as his role solidified, but the signal kept flickering. On July 12, we upgraded him to watch again at 0% ownership. On July 23, same call. Now, with a sustained stretch of production and consistent at-bats, the data is clear: the signal has only strengthened. Ownership has tripled from 1% to 3% in about a week. Managers who've been following WaiverScout's tracking have had weeks of lead time on this.

The Numbers Back It Up

Let's walk through the rolling windows. Over the last 7 days, Monasterio posted a .320 AVG with a .415 wOBA across 29 plate appearances — that's not a one-game spike, that's steady production over a full week of regular playing time. Pull back to 14 days and the picture gets even better: a .378 AVG, .449 wOBA, 50% hard-hit rate, and 90.2 mph average exit velocity over 44 PA. The 30-day view holds up beautifully — .344 AVG, .441 wOBA, 3 home runs, a steal, and a 55.6% hard-hit rate at 92.7 mph EV across 72 PA.

That 30-day hard-hit rate is the number that matters most here. A 55.6% hard-hit rate paired with 92.7 mph exit velocity tells you this isn't hollow batting average. He's squaring the ball up consistently, and the quality of contact is legitimate.

Plate Discipline Checks Out

The walk rate has held steady around 11% across all three windows (10.3% in 7D, 11.4% in 14D, 11.1% in 30D). The strikeout rate is manageable and has actually trended down — from 24.1% over the last week to 18.1% over 30 days. That's the trajectory you want to see: a hitter sharpening his approach as he gets more comfortable with consistent playing time.

Opportunity Is Real

Monasterio has logged 29 PA in the last seven days. Boston is giving him the runway. His four-position eligibility means he's not dependent on one lineup spot to stay in the mix, and as Yahoo Sports noted, he's been a fixture in the Red Sox lineup recently. That versatility is a fantasy asset in itself — especially in leagues where roster flexibility determines matchup wins.

For managers looking at the same position space, Ernie Clement occupies a similar role but hasn't generated the same caliber of batted-ball data. Monasterio's exit velocity and hard-hit numbers separate him clearly.

The Verdict: Watch

Monasterio is a watch, not an add — yet. Here's why: 44 PA is a solid enough sample to say the skills are real, but we want to see if the playing time holds through August. The hard-hit data and exit velocity support the production. The plate discipline is sound. The opportunity is there right now. If you're in a deeper league (14+ teams) or need multi-position flexibility, this is closer to an add. In standard 12-team formats, keep him at the top of your watch list and be ready to move the moment another strong week confirms the trend. At 3% rostered, you likely have a few more days before the rush — but FantasyPros is already picking up on the hot streak. Don't wait until he's at 15%.
