Submarine Arm Slot Advantages
Lopez’s submarine release point flattened his arm slot, reducing the typical overuse stress on his shoulder and giving his pitches a unique trajectory. This angle made his curveball bite late and kept hitters off balance.

He built a reputation for throwing strikes in tight counts, relying on precise placement rather than sheer velocity. His ability to repeat his motion contributed to low walk rates across his career.

With the Giants, Lopez became a key long relief and setup option, helping stabilize the bullpen during critical stretches. His strong performances in 2010 and 2012 were integral to two World Series championships.

In Boston, he served as a dependable lefty out of the pen, mentoring younger relievers and providing stability in high leverage situations. His experience shaped clubhouse culture during competitive seasons.
Technical Breakdown And Scouting Insights
Curveball As A Primary Strikeout Tool
His curveball, thrown with sharp downward action, generated swings and misses at an elite rate. The pitch remained effective even late in games because of his consistent spin and release point.

Standing 5 feet 7 inches, Lopez relied on mechanics and sequencing rather than raw arm strength. His maintenance focused on flexibility, core stability, and careful monitoring to preserve his workload over many seasons.
