Hey, everyone. Well, tonight i played with one of my hitting partners after returning to tennis last week after a month off due to tendinitis. Last time I played him, which was in November, I won a set 6-4, and a tiebreaker 7-4. However, he's been working with his coach on his first serve and has amped it up to around 115 mph with a moderate amount of various spins. It was not so much that his serve was good, but mine was bad. He could hold so easily against me, while my first was only about 65 mph. Because of this, he double bageled me. I was happy with my ground game, but I need to amp up my first serve to match him. I'm about 5 foot 5, and I'm aiming for 100 in the next 2 months. What to do?
