I have a six year-old son, so I get questions like this asked of me all the time. Thank goodness, then, that there are people like Randall Munroe of XKCD to answer it. Here’s what, among other things, would happen if a pitcher could throw a baseball at the speed of light:
These gamma rays and debris expand outward in a bubble centered on the pitcher’s mound. They start to tear apart the molecules in the air, ripping the electrons from the nuclei and turning the air in the stadium into an expanding bubble of incandescent plasma. The wall of this bubble approaches the batter at about the speed of light—only slightly ahead of the ball itself.
Which is why Greg Maddux chose to only hit the low 90s with his fastball back in the day.
Dodgers southpaw Clayton Kershaw is nearing his return to the mound, according to club manager Dave Roberts. Both Kershaw (left biceps tendinitis) and fellow lefty Rich Hill (left middle finger blister) are scheduled to toss simulated games on Saturday; depending on the outcome, Roberts says Kershaw could forgo a minor league assignment and slot back into the rotation by Thursday.
Kershaw, 30, was diagnosed with biceps tendinitis as the team closed out their Mexico Series at the start of the month. He has not made a start in several weeks, but was finally able to resume throwing on Sunday and managed to get through two successful bullpen sessions. Though Dodgers’ ace hasn’t been completely injury-free over his 11-year career in the majors, this is the first significant issue he’s had with his pitching arm so far. The team is expected to take every precaution with the lefty, and will likely limit him to just four innings during Saturday’s simulated game.
Prior to his injury, Kershaw was working on another dominant run with the club, sporting a 2.86 ERA, 2.0 BB/9 and 9.8 SO/9 through his first 44 innings of the season. While Kershaw, Hill and left-handed starter Hyun-Jin Ryu served their respective terms on the disabled list this month, the Dodgers utilized a combination of relievers Ross Stripling and Brock Stewart, both of whom impressed during their limited time in the rotation.
